Application led Kay 26, 1920. Serial No. 384,446.

To all whom t may concern.'

Be it known that I, THOMAS (j. JONES, a citizen of the vUnited States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Valve, of which the following is a speci' ered or entirely covere andan index tin# ger or pointer on the casing with which either of said characteristics is to register for accuracy in the adjustment of said member.

rl.`he invention is satisfactorily illustrated in the accompanying drawing, but the importantv instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims,

Figure 1 represents a side elevation of a valve embodying my invention.

Fig. 2\represents a central longitudinal section thereof Online 2-2 Fig. 1.

Fig. 3 represents a horizontal section on line 3 3 Fig. 2. v

VFi 4-represents a side elevation of the mova le memberof the valve.

Fig. 5 representsw'a top or plan view of a washer employed. j

Fig. 6 represents a section on line 6-6 imilar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings 1 designates the body or casing of the valve and 2 designates the movablemember therein, the latter occupying said body and being hollow and cut-away partlyon its side forming the spiral edge 3 acting as a variable port whereby a eater or ess amount of water or other lui may enter said member from the inlet nozzle 4 and be dischar ed in the same proportion at the outlet nozz e 5 and so a variable amount of water or other fluid may be admitted into the member 2 and discharged therefrom and the casing to say a radiator or other obj ect to which the water or fluid isto be directed, the part 2X of the l member being adapted to be covered by the solid wall of the casing whereby the discharge of iuid is cut off, see Fig. 6.

6 designates a knob-like member forming a handle which is fitted on the outer side of the cup or inverted cap 7 and secured thereto by the screws 8, said cup having on its inner side the lugs 9 which are adapted to be engaged by the washer 10 which consists of a disk of metal or other material having in its periphery the recesses 11, which are adapted to have said lugs9 enter the same, thus preventing rotary movement of said washer.

12 designates a bolt which is connected centrally with the top wall 13 of the movable member 2 of the valve, passed throu h the top 14 of the casing 1, the base 15 of t e cup 7 and the washer 10, its` threaded end which is above having thereon the jam nut 16 which is adapted to tighten against the upper side of the washer 10 whereby by rotating the knob 6 rotary motion may be imparted to the cup 7, the Washer 10, the bolt 12 and consequently the member 2 and thus the latter may be turned to the required extent to cause a larger or smaller volume of water or Huid to pass intothe member and be discharged therefrom or to be entirely cut off from entering or leaving the valve, this being due to the position of the s iral edge of the member 2 relatively to the 1nlet and outlet nozzles of the device.

l -Interposed between' the underside of the washer 10 and the upper side Of"the base 15 of the cup 7 is the coil spring 17 which surrounds the ad'acent portion of the bolt 12 and is adapte to be adjusted in tension by the action of the nut 16 whereby thetop wall ofthe movable member 2 may engage frictionally to a greater or less extent with the underside of the ton wall 14 of the casing 1, so as to form a iluid tight joint for said walls and prevent leakage of duid thereat, itA being noticed that when the screws 8 are released from the side of the cup 7 the knob 6 may be removed, and thus access is had to the nut 16 for adjusting the tension of the spring 17, and the removal of the washer and saidispring if desired. On the underside of the knob 6 is a lining device,

'said hollow member and passing into said gageable with said cup,

` of variable size,

18 of asbestos with which -the peripheral wall of the cup is adapted to contact thus serving to keep said knob'in cool condition.

On the exterior side of the rim of the knob 6 there are numerals 19 or other characteristics which are spaced apart around said rim and on the exterior side of the casing 1 is the index finger 20 whichv is cast therewith flat thereon and is adapted to point to either of said numerals, both numerals and index finger being most plainly visible from the side of the device, so as to guide an operator in pro erly rotating the movable member 2 ci) the valve, whereby the amount of fluid that is admitted into said member and discharged therefrom may be set, it being evident that when the port formed-by the edge 3 of the cutaway portion of the member is entirely covered by the solid portion of the wall of the casing it is indicated. by 'zero being at the point of the index, and so showing that the fluid is out off, and the valve is not in operation.

Having -thus described my invention what I claim as new and deslre to secure by Letters Patent, is

1. In a valve, a casing, a rotatable hollow member therein, the side wall of said member being cut away partly forming a port of variable size for the admission and discharge of fluid into and from said member in different volumes, a rotatable handle-like device on said casing adapted to be connected with said member for operating thelatter, and a cup-likegmember on said casing and being connected with said handle-like a bolt-like member connected with cup, a washer on said bolt-like member enand a tightening device yon said bolt-like member adapted to engage said washer.

2. In a valve, a casing, a hollow 'rotatable member therein, the side wall of said member being` cut away partly forming a port a cup on said casing, a connecting bolt for said member with said cas" said rotatable member,

pressure on said member on the a jacent wall of'said casing.

3. In a valve, a casing, a rotatable hollow member therein, the side of the latter having therein -a port of variable size, a cup on said casing, a washer on said cup, a bolt in said washer adapted to pass through said cup and the top of said casing and connectible with said member, vice on said bolt adapted to be seated on said washer. i

4. In a valve,'a casing, a rotatable member therein,- ythe side of the latter having therein a port, a cup on said casing, a washer in said cup, a bolt adantedfto be passed through said washer and connectible with s aid rotatable member, said cup having thereon lugs with which tion of said washer is engageable, and a nut on said bolt adapted to be seated on said washer.

5. In a valve, a casing, a rotatablemember therein, the side of the latter having therein a port, acup on said casing, a washer in said cup, a bolt adapted to be passed through said washer and connectible with said cup having thereon lugs with which the peripheral portion of said washer is engageable, a nut on said bolt adapted to be seated on said washer, and resilient means interposed between said washer and a portion of said cup.

6. Ina valve of the character stated a casing, a movable member therein, and a knob mounted on said casing adapted to rotate said member, i underside a lining -of asbestos adapted to have the wall of the member to which the knob (is aiixed contact therewith and so serve to keep said knob in comparatively cool condition.
